摘　　要：利用脉冲激光验证高速脉宽调制控制器(Pulse Width Modulator,PWM)单粒子瞬态效应的敏感性和防护设计。试验中,通过改变脉冲激光能量,逐步扫描PWM控制器电路,确定了诱发单粒子瞬态效应的激光能量阈值和敏感区域。通过改变PWM控制器软启动配置电路设计,验证了防护电路设计的合理性,为卫星电源子系统的单粒子瞬态效应防护设计提供技术参考。Sensibility and protective design of single event transient effect for Pulse Width Modulator(PWM)was validated by pulse laser.During test,by changing the energy of the pulse laser and scanning the PWM circuit step by step,the energy threshold of the pulse laser and the sensitive region of PWM induced single event transient effect were determined.By changing the soft start configuration circuit design of PWM,the rationality of the protection circuit design was verified,which provided a technical reference for the single event transient protection design of satellite power subsystems.
